SanDisk 32GB microSDHC Class 4 Card

This is a 32GB microSDHC memory card rated at Speed Class 4. It is suited for users who need basic removable storage for devices such as older cameras, dash cams, or feature phones that accept the microSDHC format. The package includes a standard SD adapter so the card can also be used in full-size SD slots. An OEM USB 2.0 card reader is bundled for immediate data transfer to a computer.

Class 4 speed rating

The single specification that decides suitability is the Class 4 rating, which guarantees a minimum sustained write speed of 4 MB/s. This level is adequate for standard-definition video recording, photo capture, and general file storage. It will not meet the minimum write-speed requirements for high-definition or 4K video workflows, nor for applications that demand faster sequential performance such as running operating systems or loading large game assets.

Simple plug-and-play installation

Insert the microSD card into the supplied USB 2.0 reader and connect the reader to a free USB port; the host system will recognise the card as a removable drive without extra drivers. The card also fits directly into any microSDHC or SDHC slot when used with the included adapter. A common issue is attempting to record high-bitrate video, which can cause dropped frames or recording errors because the Class 4 sustained write limit is exceeded.

Questions about this item

What does the Class 4 rating mean for everyday use in a phone or camera?

Class 4 guarantees a minimum sustained write speed of 4 MB/s, which is enough for standard-definition video recording and basic photo storage on a 32 GB card.

How fast can the included USB 2.0 reader actually move data to my computer?

The reader uses a USB 2.0 connection, so file transfers between the card and your PC are limited to the USB 2.0 bus speed.

Will this microSDHC card and reader work with my laptop's full-size SD slot?

The bundle includes a microSD-to-SD adapter, letting you insert the 32 GB card into any standard SD slot, and the USB reader plugs into a Type-A port.
